Loss off network shares on 8.2

[Phosphoric]

@Phosphoric

I have tried to replicate your network environment as closely as possible. In a nutshell, I'm unable to repro your issue.

Among the 2 dozen different devices on my LAN, I now have

1. my Linux Mint laptop
2. an RPi3A running as a moOde 8.2.2 player (let's call it 'A') which I'll use as an SMB client
3. a CM4 running as another moOde 8.2.2 player (let's call it 'B'). There's a USB thumb drive which is being served via SMB file sharing from this host (let's call the share 'B-Music').
4. an RPi3B running OMV 5.6.26-1 (let's call it 'C'). The SMB service on this host is enabled and serving a Music share (let's call the share 'C-Music').

From the moOde player A I can mount both B-Music and C-Music SMB file shares and see all their contents in A's Library views.

On the Linux Mint laptop, I can use the Caja File Manager to browse the network and see host B and host C. I can click on either one, then click on the Music share offered, and browse its contents.

Candidly, I did not expect otherwise, since this is how the SMB scheme is supposed to work. It seems to me that you may be having some sort of LAN-level issue, perhaps even at the router, which is causing the symptoms you describe. The first thought I had was perhaps it has to do with DNS/mDNS namespaces but that's pure speculation.

PS - about that OMV 5.6.26-1. I spent more time than I want to admit trying to build OMV on the latest raspbios lite x64 using the OMV install script (which their Wiki says would have resulted in OMV 6.0.x) and failed. Trying, instead to build OMV on the latest raspbios lite armhf (e.g., 32-bit) using the OMV install script worked first time out of the gate, resulting in OMV 5.6.26-1. All moOde players and the LMT are running 64-bit OSes.

Thank you once again Kent for spending so much time on my problem.  To be honest I've been somewhat distracted the whole weekend after trying to upgrade from OMV5 to OMV6.  It was a complete disaster and in trying to fix it, I managed to trash more and more of my system.  I gave up after several trys at OMV6, it appears to be too unstable for me.  It took a great deal of effort also to get the permissions right so that I could browse my shares via my Linux Mint pc.  Currently working my way back to recovering OMV5.  A very depressing weekend.

Just one point on your experiment, you were able to view all of those shares from different sources.  I am able to do that but can't write to them.
As usual, whilst my RPI NAS was off line, the mo0de shares became writeable again.  Really weird.
Thanks again
